EN10297 Core Analysis of Seamless Steel Tubes for Mechanical and Engineering Applications

1、 Standard Overview

Scope of application: EN10297 is a European standard that specifically specifies the technical requirements for seamless steel pipes for mechanical manufacturing and general engineering purposes, covering materials, production processes, and testing standards. It is applicable to non alloy steel, alloy steel, and stainless steel seamless pipes.

Version division:

Part 1 (EN10297-1): For non alloy steel and alloy steel pipes (such as E355), specify the mechanical properties, chemical composition, and processing technology;

Part 2 (EN10297-2): Focusing on seamless stainless steel pipes (such as TP304, TP316L), emphasizing corrosion resistance and adaptability to high/low temperature environments.

2、 Material and Technical Requirements

Material classification:

Non alloy/alloy steel: including E355 (carbon steel), S355J2H (fine grain steel), suitable for high load mechanical components (such as transmission shafts, hydraulic supports);

Stainless steel: such as 316L, 317L, etc., meet the requirements of corrosive scenarios such as food processing and petrochemical equipment.

Core indicators:

Chemical composition: Strictly limit the content of carbon (C), chromium (Cr), nickel (Ni) and other elements to ensure material properties;

Mechanical properties: tensile strength (≥ 420MPa~≥ 750MPa), yield strength (≥ 235MPa~≥ 550MPa), and elongation (≥ 15%~30%);

Processing technology: Hot rolling or cold drawing forming, surface treatment including polishing, sandblasting or black coating.

3、 Application Fields

Mechanical manufacturing: automotive parts (such as steering shafts), engineering machinery components (such as bearing sleeves);

Industrial equipment: chemical reactor pipelines, heat exchanger bundles, and food processing equipment conveying pipes;

Special scenarios: Low temperature environments (such as LNG equipment) and high-pressure vessels (requiring ultrasonic testing to verify defect free).

4、 Market and Certification

Export requirements: Must comply with EN10297 standard and EU CE certification. Some products must be accompanied by mechanical performance testing reports and material certificates.

The above content integrates the core requirements and market practices of EN10297 standard, and the referenced information is based on publicly available specification documents and manufacturer technical documents.
